(MUSICAL CINEMA EXTRAVAGANZA) It's a most promising pairing: Busby Berkeley, the cinema-choreography genius of the 1930s, and Chris Jeffries, Seattle's beloved theatrical composer and first-ever Stranger Genius Award winner for theater. For Kaleidoscope Eyes: Songs for Busby Berkeley, Jeffries has written a series of new songs that he'll perform live to 16 of Berkeley's greatest film sequences, packed with dazzling dames, breathtaking visual spectacle, and, if we're lucky, at least one roller-skating baby.
